Title: Driving circuit for rotary transformer
Inventor: KATO MASAAKI
IPC: G11B5/02
Filed: 1987-12-15
Abstract: PURPOSE:To transmit a signal without distortion by providing a voltage detecting means on the final stage of a driving circuit and controlling a current value on an emitter side by a voltage detected by an element on a collector side. CONSTITUTION:A driving circuit 1 detects the voltage proportionate to a load current by a resistor 13, it is level-shifted by a transistor (TR) 20, a resistor 19 and a current source 18 to constitute an emitter follower and it is impressed on the base of a TR 16. The TR 16 constitutes a current source to control a collector current by a resistor 17 and the base of the TR 16. The current source controls the emitter current of a TR 12 of the emitter follower. When a current to flow into from an output terminal 15 becomes larger, the collector current of the TR 16 is increased and a current to flow into the output terminal 15 is increased. On the other hand, the collector voltage of the TR 12 increases by decreasing the reactance of a rotary transformer 32 when the frequency of an input signal lowers and the voltage increased at the low frequency can be outputted without the distortion.
